GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 400,171, dated March 26, 1889.

Application filed July 2, 1888. Serial No. 278,734. (No model.)

To all whom it may concern.-

Be it known that I, HAROLD J. BELL, a citizen of the United States, residing at Gloucester City, in the county of Camden and State of New Jersey, have in vented new and useful Improvements in Gas-Governors, of which the fol into the shell 2, whence it passes to a burner- 55 lowing is a specification.

My invention consists in a gas-governor or gas -regulating burner of the construction IO hereinafter described and claimed.

In the annexed drawings, Figure 1 is a sectional elevation of a gas-regulating burner embodying my invention. Fig. 2 is a plan of the base with its cup and central stem.

Fig. 3 is an inverted plan of the float-valve.

The numeral 1 designates the base of the burner-shell, and 2 the upper part of said shell. The base or lower part, 1, is formed with an internally-threaded neck, 3, for atze tachment to a gas fixtureg a flange, at, on which the lower end of the part 2 rests; a cup or opentop annular chamber, 5, which is externally screw threaded to engage internal screwthreads n the lower end of the part 2, and a 2 5 tubular stem, 6, which rises from the center of said cup and communicates with the interior of the neck that is attached to the gasfixture.

Surrounding the base of the tubular stem 6 is an annular shoulder, 7, which normally supports a float-valve, 8, that surrounds the tubular stem 6 and controls a gas exit or exits, 9, formed therein. The upper end of the tubular stem 6 is closed and supports a vertical guide, 10, 011 which the float 8 moves. The float-valve 8 is approximately bell-shaped and flares downward and outward, its lower end being inclined outward and slightly upward to form an annular lip, 11, which approachesbut does not come in contact with the wall of the cup or chamber 5, an annular gaspassage, 12, being thus formed between said float and the wall of the cup.

lVithin the outer flaring shell of the float is a vertically-depending tube, 13, the lower end of which forms an annular valve, 14, that closely surrounds the tubular stem 6. In the upper part of the tube 13 are gas-exits 15. The

gas that enters the tubular stem 6 passes out through the exits 9 into the tube 13, thence through the exits 15 into the outer flaring portion of the float 8 downward into the cup 5, and thence beneath and around the float-lip 11 and out through the annular passage 12 tip, 16, supported in the upper end of said shell. The lower end of the tube 13 projects slightly below the float 8 and normally rests on the shoulder 7; but under the pressure of gas the float and tube rise, and if the pressme of gas becomes excessive the annular valve 14 is carried upward sufficiently far to more or less cover the exits 9, diminish the flow of gas, and automatically regulate its pressure at the burner. In order to prevent the float 8 from rising so far as to become dis engaged from the guide 10, a wire, 17, is passed through the upper end of said guide to form a stop.

The operation of the device will be readily 7o understood from the foregoing description, in connection with the arrows in Fig. 1, indicating the course of the gas-current.

In concurrent applications, Serial Nos. 278,732, 278,733, and 278,737, of even date herewith, I have shown gas-regulators comprising a two-part shell having an internal tubular stem closed at its top, provided with lateral gas-exits, and having on its upper end a vertical guide for a flaring conical float which op erates in a cup surrounding the base of said tubular stem, the float being provided with an internal tubular valve to control the gas-exits of the stem. This construction is claimed in my said application Serial No. 278,737. In each of said above-mentioned applications the float-valve is shown with a lower flaring end which fits somewhat closely in the surrounding cup without binding therein, and a gaspassage to the burner is afforded through an 0 opening in the bottom of the cup, which is controlled by an adj ustin g-screw in the base of the regulator. According to my present invention, the adj usting-screw and the opening in the bottom of the cup are dispensed with, 5 and the flaring lower end or lip, 11, of the floatvalve 8 is fitted so loosely in the surrounding rated tube 13, an annular gas-passage, 12,1)0 IO cup 5 as to afford an annular gas-passage, l2, ing' provided between. the said lip and cup,

between said lip and cup. substantially as described.
